If you follow IMSA racing (International Motor Sports Association), you may have heard about Mazda Motorsports’ newest engine design, the MZ-2.0T. This new engine incorporates some pretty cool tech to keep the Mazda team in serious contention of the F1 circuit. Here are some things to know about the new design. It might seem like alphabet soup, but the MZ-2.0T is pretty straight forward. The “MZ” is a nod to Mazda, “2.0” refers to the engine’s two-liter capacity, and “T” connotes the engine’s turbocharger.

What Makes the MZ-2.0T so Special?

This new design will revolutionize the construction of racing engines. For one thing, Mazda Motorsports is preparing for a new IMSA rule that bans diesel fuel effective for the 2017 season. As a result, Mazda decided the purpose-built engine was way to go. Jonathan Bomarito, one of the drivers who tested out the engine, explained to MazdaUSA, “The drivability of the engine is incredible. The first thing you notice is how smooth the power is delivered in every gear through the RPM range. There is great low-end torque with zero turbo-lag, which is very impressive. All race tracks are different and the gearing is never perfect for every corner, so having an engine where you can short-shift or stretch a gear longer is very important. The MZ-2.0T does this easily.”

In Action

The MZ-2.0T made its debut August 4-7 at the Continental Tire Road Race Showcase at Road America in Elkhart Lake, Wisconsin. After leading the race for a total of 34 laps, Jonathan Bomarito in Mazda’s No. 55 car took 5th place overall. Not a bad start for the brand new engine. The next race will be September 16-17 at Circuit of the Americas in Austin, Texas.
